5309.29.40 - Other

This HTS category, 5309.29.40, encompasses woven fabrics of flax that contain less than 85 percent by weight of flax, and are not specifically classified under other "other" subheadings within the 5309.29.40 branch. Crucially, this designation applies to woven flax fabrics that do not fall into the preceding sibling category, 5309.29.30, which specifically covers such fabrics containing cotton and man-made fibers. Therefore, this classification serves as a residual category for woven flax fabrics meeting the general criteria but lacking the specific compositional elements of its siblings.

The distinction from sibling categories is paramount for accurate classification. While 5309.29.30 is reserved for blended flax fabrics containing cotton and man-made fibers, this category, 5309.29.40, is for woven flax fabrics that are either 100% flax or blended with other vegetable fibers or animal-origin fibers, provided they still meet the less than 85% flax weight requirement and are not specifically itemized elsewhere. This ensures that the composition, beyond the presence of cotton and man-made fibers, dictates its placement.

The subcategories within 5309.29.40 further refine the classification based on a physical characteristic: width. The primary subdivision distinguishes between fabrics with a width exceeding 127 cm (represented by 5309.29.40.10) and those that do not meet this width criterion, classified under "Other" (5309.29.40.90). This demonstrates that for woven flax fabrics falling into this residual "other" category, the dimension of the fabric plays a role in its final, detailed HTS classification.
